Intel would like to thank NVIDIA Product Security Team (CVE-2020-24486) and Intel employee Hareesh Khattri (CVE-2020-12357) for their reports.
Intel, and nearly the entire technology industry, follows a disclosure practice called Coordinated Disclosure, under which a cybersecurity vulnerability is generally publicly disclosed only after mitigations are available.
